Abstract
A method for performing channel estimation in an orthogonal frequency division multiplexing (OFDM) signal includes choosing reserved tones to be part of a pilot pattern, and using the reserved tones in the pilot pattern to perform the channel estimation. An apparatus for use in performing channel estimation in an OFDM system includes a receiver configured to receive a transmitted OFDM signal; a pilot symbol extractor configured to extract pilot symbols from the OFDM signal; and a channel estimator configured to perform the channel estimation, including using reserved tones as pilot tones.
